"more than one" prefixes in one thread

I mean, some "thread themes" or names are compatible with two or more prefixes I created and It would be great to have possibility to add two or more prefixes when "create the thread"

for example:
in my forum will be list of microphones and prefixes will be "groups of instruments" you can use it with: guitars, cymbals, vocals, etc.
some microphones can be used in recording guitars and vocals, too
thats why I need more than one prefix :)
